The given circuit are oscillator.
Important points in oscillator by making postive feedback or phase shift 180 degree even without input ac there will be sustained oscillation in the circuit.
Doubt may come with out input how can oscillator produce output waveform actually it takes energy from DC signal given fir biasing and uses it to produce output.
General procedure to solve is to may the phase shift in feedback path as 180 degree.
And then solve by using network analysis and put imaginary part =o to get relation for frequency since at 180 degree phase shift imaginary part is zero.
The frequency is derived in above problem using this criteria only.
